Pressure Sensors, Transducers

1. Overview

Pressure sensors and transducers are devices that convert mechanical pressure signals into electrical outputs. They serve as critical components in monitoring and controlling pressure in various systems. Modern industrial automation, medical diagnostics, and automotive safety systems rely on their precise measurements to ensure operational efficiency and safety.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Strain Gauge	High accuracy, stable output, requires bridge circuit	Industrial machinery, load cells
Piezoresistive	Miniaturized design, high sensitivity, temperature-dependent	Medical blood pressure monitors
Capacitive	Low power consumption, corrosion-resistant, nonlinear output	Aerospace altitude sensors
Piezoelectric	Self-generating, dynamic pressure measurement	Engine combustion analysis
Optical Fiber	Immune to EMI, suitable for harsh environments	Oil well downhole monitoring

3. Structure and Components

Typical components include:

Pressure port (stainless steel/ceramic diaphragm)
Sensing element (MEMS silicon chip, strain gauge)
Signal conditioning circuit (amplifier, ADC)
